In a diploid organism, two homologous chromosomes synapse at prophase 1 of meiosis. One of the homologous chromosomes carries a sequence of four genes named A, B, C, and D. They get capital letters because each gene is dominant. On the two chromatids of the homologous chromosome, the same sequence of genes are all recessive. They are denoted a, b, c, and d. During prophase I of meiosis, when the homologous chromosomes synapse with one another, there is a crossover between two of the non-sister chromatid. These two chromatids break between genes B and C, as shown in the diagram below. They then reattach to the non-sister chromatid. What will each of these 2 chromatids carry after they separate from their sister chromatid in meiosis 2?
